YM3220
In the normal Yanmar fashion, there should of been a YM3120 to compliment the YM3110. A YM3120 would of used the same engine as the YM3110, but had the -20 options. The YM3120 never made it. Yet here we are with a YM3220 with no sibling called the YM3210. One could say the YM3110 and the YM3220 are their own siblings, just a tad out of sequence. Both use the 3T84 engine. Indeed a mystery why Yanmar went this route. It's not like 1Hp would of made all that difference either.
Finding the engine ID plate was not an easy task. This image had to be enhanced just to read it.
The best images of the YM3220 came from a person who bought it from a UTDA dealer down south in the USA. Take note the side engine skirts are painted tractor red like the other panels. This aligns to the factory intent as well and not a mistake. Prior models typically had those engine skirts painted Yanmar off-white.
Additionally, this model has the JD950 looking rear fenders and the original Yanmar step up that John Deere then included in their larger 50 Series machines, then the 55 Series and 90 Series Yanmar had made as well. This is really a bent 19mm [3/4-inch] solid bar with the ends flattend and two mounting holes for large bolts to mount.
Here's the same YM3220 still in Japan untouched by any refurb or restoration facilities in North America. Note the UFO at the bottom from the front grill. This is very important.
The UFO becomes a very popular selling point on the FX FORTE series machines and the most sought after in Japan from any manufacture of tractors. UFO is a computerized link-up to the Yanmar tiller on the 3PT. It's much more than draft control, it handles tine rotation forwards or backward within certain tiller tine groupings, adjusts tiller tine speeds (not the PTO output), allows the tiller to curl towards the tractor or away (similar to a top-link with hydraulics) and much more.
The UFO function here is an early version. Possible less functions than the FX Series. Yet, incredible to see it here on this model.
The best image found at the time showing the UFO controls on the top rear fender.
Sorry it's just a glimpse. And notice the factory PowerSteering decal on this model.
Like most of the -20 models comes the push dash with all the fancy gauges and controls.
This image is a rare one as it shows a clear view of the center console. Most of the time images are taken with the steering wheel in the way.
The other dash gauges. Shift is on the column too.
In Japan, the YM2500 model frame and up could use the canopy open cab. Here is a YM3220 with one. Also take note of the divider wall behind the seat. Some of the US YM Series came with this wall as well. A Yanmar tool box mounts onto it. Often we see this tool box in the Parts Manuals.
Out of all the Yanmar -20 models, this is one of the ideal machines to own. Only the more rare to us here in the USA is the YM4220 with the
Turbo that is probably the best of all the -20 models Yanmar ever made.
If I had to pick a YM model with all the loaded features, it would be the YM3220 or YM4220. These two are the last of the -20 model family. The icing on the cake actually.
Here's the BONUS. The 3T84 engine used is also used in the YM336.
See attachment for the engine parts manual as a good reference. It will show what is shared and what is slightly different.
Both are PowerShift, yet the YM336 has the controls on the floor like the YM2610.
Additionally the YM276 with the 3T84 engine has a Service Manual free on the web. Another good reason why the YM3220 is a smart choice to own.
